Happy Science Monday! We want to share with you a cool science experiment that you can do at home with the kids. If you have ever wanted to see your favorite flower in different colors, then this is the experiment for you. This fun and colorful experiment will teach kids about the basics of plant biology and primary colors. This experiment also teaches kids how those patels change into different colors, which is the process of the transportation of water. There are three factors to explain this: Capillary action, Cohesion, and Transpiration. For further explanation of the three factors, please refer to the original site, which the link is attached under the picture.

What you need for the experiment:
What you need for the experiment:
- white flowers such as daisies or hydrangeas (we used long stemmed white roses)
- food coloring
- several glasses, vases or test tubes if you want to see the colored water from the outside. Otherwise, you can use plastic cups.
- Fill each glass with fresh water from the tap. Put 2-5 drops of food coloring into it, one color each. You can also mix the colors (e.g. blue + yellow = green) to get all the rainbow colors.
- Trim at least half an inch of stem off the flowers before putting each into the glass and each time you change the water.
- Add flower food if it is provided.
- Keep them in a cool place overnight.
- Observe the change in colors in the petals.
- If you use flowers such as daisies that take longer to do this experiment, change the water entirely every 2-3 days to keep the flowers fresh for longer.
